Title: Scanning mechanism of on-vehicle radar equipment
Inventor: TAKAHARA TOSHIYUKI
IPC: G01S13/931
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To improve the angle accuracy of a scanning mechanism in the forward direction of a vehicle by making the scanning speed of the mechanism in the direction slower by providing a first noncircular gear attached to an input shaft, a second noncircular gear meshed with the first gear, and a connecting link which is connected to an eccentric pin provided on the second gear on one side and the transmitting-receiving section of an antenna on the other side. SOLUTION: An input shaft 16 is rotated at a constant speed by means of a motor and a speed reducing mechanism. The constant-speed rotating motion of the shaft 16 is transmitted to a rotating shaft 18 after the motion is converted into irregular-speed rotating motions by means of the rotation speed converting action of first and second noncircular gears 17 and 19. An eccentric pin 15 integrally formed with the shaft 18 periodically changes by making rotating motions along a circle (r). Since one end of a connecting link 14 is connected to the pin 15 and the other end is connected to a connecting pin 13 at the transmitting-receiving section 1 of an antenna, the receiving section 1 continuously scans the transmitting-receiving direction of radio waves while the section 1 makes swinging motions around a swinging shaft 12.  When the swinging angle θ of the section 1 changes, the speed of the section 1 becomes faster in the forward direction and the angle accuracy in the forward direction is improved.

Title: Temperature self-compensation type crystal resonator
Inventor: AZUMA YOSHIAKI
IPC: H03H9/19
Filed: 1993-07-30
Abstract: PURPOSE:To control temperature characteristics and to compensate a temperature in a single resonator by combining main-vibration and sub-vibration in an AT plate crystal resonator. CONSTITUTION:In the AT plate crystal resonator 1 provided with the vibration modes of the main vibration which is thickness-shear vibration and the sub-vibration which is high-order contour system vibration, an electrode 3 is provided on the surface of a crystal plate 2. The crystal plate 2 15 formed while providing a prescribed crystal plate width W0 and the electrode 3 is positioned on the surface of the crystal plate and formed while providing a prescribed width W1. Since the frequency temperature characteristics of the main-vibration changes while drawing a cubic curve and the frequency temperature characteristics of the sub-vibration for which temperature dependency is extremely high rapidly changes while drawing a linear curve, the sub- vibration is combined with the main-vibration when the two vibration modes simultaneously occur. Thus, a temperature compensation function is added to the resonator 1 by utilizing the characteristics, only a part for which temperature compensation is required is changed while utilizing the frequency temperature characteristics of the main-vibration and the desired frequency temperature characteristics are obtained.
